The Spanish international escaped punishment, despite appearing to stamp on Emre Can in the 12th minute AND Martin Skrtel in the second half.

The second incident in this Capital One Cup semi-final second leg was clearly missed by referee Michael Oliver.

And it seems likely the FA will take action in the build-up to Saturday's visit of champions Manchester City.

Starsport can also reveal Blues boss Jose Mourinho is set to find out prior to the title cruncher what punishment the FA have dished out to him following his misconduct charge.

The FA acted after the Portuguese coach claimed there was a campaign against his men, with so many decisions going against them.

Liverpool boss Brendan Rodgers hit out at Costa, saying: "He is an outstanding player, but he has this edge to him.

"The Emre Can incident was poor. He could have hurt a young player there. He directs his studs to his ankle, as he did with Martin Skrtel. The officials clearly didn't see it.

There's no need to do it. That's the sad thing. It's poor from him, because he's a top-class player."

“If today we played two hours of football and we lose, I would be unhappy. Fatigue is not something I am going to talk about after this game”

Chelsea manager Jose Mourinho

Mourinho said: "I don't know what you mean by 'stamp'. I think there is a campaign on the television by a certain pundit saying Costa commits crimes. He must be nuts. I have to say it was absolutely accidental.

"We know how much that pundit 'loves' Chelsea and particularly me."

Mourinho declined to name the pundit, but Jamie Redknapp said Costa was "bang out of order".

Mourinho claimed he did not know his name as he always turned the TV off when he was on.

And he was also unhappy at Oliver for not awarding a 22ndminute penalty when Skrtel brought down Costa in the box.

He added: "It is so clear. It is difficult to accept. Even though we won the game, I have to ask myself, why?."

Mourinho said he missed Ivanovic's goal early in extra-time because he was moaning about Liverpool midfielder Lucas not getting a second yellow card.

And he added that Serbian star Ivanovic ended the match with a boot full of blood.

But he praised Rodgers' team, adding: "For me, Liverpool were very good. Praise to Brendan for changing the team after their season did not start very good. They are back at the top level."

He also revealed Cesc Fabregas had asked to come off because he feared a hamstring problem after a collision with skipper John Terry.

Turning ahead to City, he said: "If today we played two hours of football and we lose, I would be unhappy. Fatigue is not something I am going to talk about after this game."
